Association of sex work and social-structural factors with non-fatal overdose among women who use drugs in Vancouver, Canada.

Background: Women who use drugs (WWUD) and engage in sex work experience disproportionate sex- and drug-related harms, such as HIV, however comparatively little is known about their overdose risk. Therefore, we examined the association between sex work and overdose and secondarily explored the association of social-structural factors, such as policing and gendered violence, with overdose.

Methods: Data were derived from two community cohort studies based in Vancouver, Canada between 2005 to 2018.

Delivered as Described: A Successful Case of Cognitive Processing Therapy With an Older Woman Veteran With PTSD.

Cognitive processing therapy (CPT) is a first-line, evidence-based treatment for posttraumatic stress disorder (PTSD). Little is known, however, about the use of CPT for older adults. As the United States population continues to grow and age, an understanding of the utility of CPT for older adults is vital.

Implementation Challenges and Disparities in Molecular Testing for Patients With Stage IV NSCLC: Perspectives from an Urban Safety-Net Hospital.

The advent of next-generation sequencing (NGS), including both tissue assays and circulating tumor DNA (ct-DNA), has been pivotal in improving outcomes for patients with non-small cell lung cancer (NSCLC). Although molecular testing is standard of care for advanced NSCLC, challenges still exist in its implementation. This Perspective examines barriers to the widespread implementation of NGS from the vantage point of a single urban safety-net institution, with a particular focus on examining racial disparities in NGS completion.

Relationships between places of residence, injury, and death: Spatial and statistical analysis of fatal opioid overdoses across Massachusetts.

Understanding the factors associated with where people who use opioids live, where their fatal overdoses occur, and where deaths are recorded can improve our knowledge of local risk environments and inform intervention planning. Through geospatial analyses of death certificate data between 2015 and 2017, we found that a majority of opioid-involved fatal overdoses in Massachusetts occurred at home. Age (adjusted odds ratio [AOR], 1.

Cyclin G1 induces maladaptive proximal tubule cell dedifferentiation and renal fibrosis through CDK5 activation.

Acute kidney injury (AKI) occurs in approximately 13% of hospitalized patients and predisposes patients to chronic kidney disease (CKD) through the AKI-to-CKD transition. Studies from our laboratory and others have demonstrated that maladaptive repair of proximal tubule cells (PTCs), including induction of dedifferentiation, G2/M cell cycle arrest, senescence, and profibrotic cytokine secretion, is a key process promoting AKI-to-CKD transition, kidney fibrosis, and CKD progression. The molecular mechanisms governing maladaptive repair and the relative contribution of dedifferentiation, G2/M arrest, and senescence to CKD remain to be resolved.

Black Race Remains Associated with Lower Eligibility for Screening Using 2021 US Preventive Services Task Force Recommendations Among Lung Cancer Patients at an Urban Safety Net Hospital.

Objective: To evaluate whether the revised US Preventive Services Task Force (USPSTF) criteria reduced inequities in lung cancer screening (LCS) eligibility among a racially diverse sample of patients with lung cancer.

Methods: This is a retrospective analysis of adults diagnosed with primary lung malignancies at an urban safety net hospital. For all patients and exclusively ever-smokers, χ tests were used to evaluate differences in LCS eligibility among socio-demographic variables using the 2013 and 2021 USPSTF criteria.

Formation of Double Stranded RNA Provokes Smooth Muscle Contractions and Structural Modifications in Bladder Ischemia.

Purpose: Growing evidence suggests that ischemia provokes detrusor overactivity and degenerative responses in the bladder. Underlying mechanisms appear to involve modification of smooth muscle contractile rudiments by hypoxia, redox, cellular stress and cell survival signaling. Downstream pathways of cellular stress and stress response molecules eliciting bladder dysfunction in ischemia remain largely elusive.

A comprehensive update to the Mycobacterium tuberculosis H37Rv reference genome.

H37Rv is the most widely used Mycobacterium tuberculosis strain, and its genome is globally used as the M. tuberculosis reference sequence. Here, we present Bact-Builder, a pipeline that uses consensus building to generate complete and accurate bacterial genome sequences and apply it to three independently cultured and sequenced H37Rv aliquots of a single laboratory stock.

A Review of Practices Around Determination of Death by Neurologic Criteria by an Organ Procurement Organization in the WAMI Region.

Background And Objective: To examine the verification of a referring hospital's practice of determining death by neurologic criteria (DNC) by an organ procurement organization (OPO) pursuant to the Center for Medicaid and Medicare Services rule §486.344(b).

Methods: In this retrospective cohort study, we examined prevalence and factors associated with deviations from acceptable DNC standards, the performance of additional ancillary testing requested by the OPO, resolution of concerns about deviations between referring hospitals and the OPO, and interactions between referring hospitals and the OPO.

Predictive functional, statistical and structural analysis of and variants linked to neurodevelopmental diseases.

Okur-Chung Neurodevelopmental Syndrome (OCNDS) and Poirier-Bienvenu Neurodevelopmental Syndrome (POBINDS) were recently identified as rare neurodevelopmental disorders. OCNDS and POBINDS are associated with heterozygous mutations in the and genes which encode CK2α, a serine/threonine protein kinase, and CK2β, a regulatory protein, respectively, which together can form a tetrameric enzyme called protein kinase CK2. A challenge in OCNDS and POBINDS is to understand the genetic basis of these diseases and the effect of the various CK2⍺ and CK2β mutations.
